Avtech AVMH-1A-C, Инструкция по эксплуатации, Страница: 21 / 29

OPTIONS
The AVMH-1A-C is available with these options:
-OS OPTION
This option allows an externally generated DC offset to be added to the output. The
desired DC offset is applied to the back panel OS terminal, which is connected to the
output centre conductor trhough a high-quality RF inductor. Do not exceed 50V, 250 mA.
When using the transformer with dual-polarity models with the “-OS” option, the external
offset must be added to the DC terminal of the inverting transformer. Do not apply the
offset to the rear-panel offset terminal on the mainframe (if present).
-M OPTION
This option provides a monitor output, which is an attenuated replica of the main output.
The monitor is connected to the main output through a 470 Ohm resistor, which results in
an attenuation of approximately 20 dB (i.e., ÷10) when the monitor output is terminated
with a 50 Ohm load.
For models with the “-OS” option, the monitor output does not include the effect of the
added offset.
The monitor output should be terminated with a 50 Ohm load.
